Does China Unicom’s 3G point-to-point SMS include inter-network messages?

Point-to-point means mobile phone number to mobile phone number (including PHS), intra-network is the number under one operator, and inter-network is the number between different operators.

For example, the connection between China Mobile and China Mobile is within the network, and the connection between China Mobile and China Unicom (PHS) is between the network.

Your sentence mainly expresses: The maximum number of free entries on the Internet is 100.

To put it in detail: (for example, if you are a mobile phone user), you and China Unicom (PHS) can send up to 100 messages for free, and the other 100 messages are only free if you send them to China Mobile numbers. (PHS) I sent 102 messages this month, so the last 2 messages will be charged according to the SMS rate between the networks. And if they are all sent to China Mobile, then up to 200 messages can be sent for free (no messages are sent to other operator numbers at all)
